RP604 Series
0.3µA IQ Low Quiescent Current 300mA Buck-Boost DCDC Converter with Synchronous Rectifier

Product Specifications

The RP604 is a buck-boost converter featuring a minimum supply current and a high efficiency at low-load. The device operates at the low operating quiescent current (IQ = 0.3 µA) to make the most of battery life for the battery driver operated intermittently.

  • The low supply current (IQ = 0.3 μA) can achieve making battery life longer and battery’s size-reduction.
  • Wide range of input voltage (1.8 V to 5.5 V) can support for every batteries from a coin-type battery to a USB port.
  • Selectable package: WLCSP-20-P2 or DFN(PLP)2730-12

  • xx … Specify the set output voltage (VSET) within the range of 1.6 V (16) to 5.2 V (52) in 0.1 V steps.
  • $ … Specify the auto-discharge function.
    A: without auto-discharge function
    B: with auto-discharge function

* Auto-discharge function quickly lowers the output voltage to 0 V, when the chip enable signal is switched from the active mode to the standby mode, by releasing the electrical charge accumulated in the external capacitor.
